The Pro Leash 6.0 from Creatures of Leisure is a versatile and strong high-performance leash for medium waves. You get here the Surefire Leash Release- This is an Injection Moulded Urethane Surefire Release Tag with molded holes – these holes allow water flow & reduce the weight of the cuff. The cord/mold connection that absorbs wave impact, stretching with the leash to resist breakage. The Leash & mold stretch up to 5 x original length. The Leash uses specially designed neo-mesh material that prevents the cuff from rotating on the ankle. Therefore it is super comfortable with a lighter & thinner cuff construction.
